What the research is about
To study and to evaluate an acoustic mobile tracking device for monitoring the migration and fate of adult Pacific Lampreys. Also to evaluate the JSATS technology for monitoring adult Pacific Lamprey movements in the Cascades Island fishway entrance.
Vast majority (84%) of adult Pacific Lamprey’s entering or released to Bonneville Reservoir rapidly and successfully passed ~80% the length of the reservoir and were detected at the Lyle gate, approximately 16 km below the Dalles Dam. This suggests that migration conditions and factors such as predation are not strongly contributing to the overall unaccounted losses in the Bonneville Reservoir during the summer and fall migration and that fish are not overwintering in the downstream two-thirds of Bonneville Reservoir.
Assurant Innovations take
The Fish Fat Meter was used to measure fish fat (lipid) and it was one of the key metrics used in this study to monitor the fish it was moved through the dams.
